Filed: 1982-01-29
Abstract: PURPOSE:To improve the quality of a circuit, by providing previously 1/n frequency characteristics to a receiver of each switching office and receiving end office when the reference level arrives in order to eliminate the frequency characteristics produced when the reception level is set at the prescribed minimum level.

Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an imaging device with a long reset time and a long pedestal time during pixel summing in an output circuit by using an asymmetrical read-out transmission clock. SOLUTION: An imaging device has an output register 10 for transmitting an image charge from an image-pickup device 6 to a clamp circuit 40 via an output circuit 2, and a PLA 30 for supplying a transmission signal to the output register 10. An output signal of the output circuit 2 includes the image information as a function of the difference between a given reference potential and an image potential. Then, both potential have each relatively constant pedestal region. A transmission signal is fed to the output register 10, so that, image charges are transmitted at a frequency of the number of times of a reset clock frequency. By changing the symmetrical characteristic of deviation of the transmission signal waveform that causes image-charge transmission, an asymmetrical deviation pattern is obtained, and thereby a pedestal region of an output can be enlarged.

Title: Vibration controller
Inventor: KAMEI NOBUO
IPC: E01D1/00
Filed: 1987-01-23
Abstract: PURPOSE:To reduce the dead zone of control through lessening frictional force by using a pneumatic bearing which generates support force in the direction of gravity and lightening the weight of a movable mass added to a rolling bearing portion which carries out the restraint of a movement direction or the like. CONSTITUTION:A pneumatic bearing 12 is provided between a movable mass 1 and a vibration body 4, and support force is generated in the gravity direction of the movable mass 1 through supplying compressed air 13 from a pneumatic pressure source 14. On account of this, when the frictional force of the pneumatic bearing 12 portion is ignored, the frictional force in the case of the pneumatic bearing 12 having been used, if, for example, support-force is chosen to be 9/10 of the weight of the movable mass 1, can even be made to be 1/10 of the old frictional force. Thus, the size of frictional force can be ignored although the movable mass equal to that of the old vibration controller is used. Accordingly, the weight of the movable mass 1 added to a rolling bearing 11 portion is lightened, and the dead zone of control can be reduced.

Title: Burst optical signal receiver
Inventor: AKIMOTO ISAO
IPC: H04B10/272
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To make the operation of the receiver stable with high accuracy by providing plural peak detection sections with different operating dynamic ranges and different gains to a peak detection circuit and operating any of the plural peak detection sections depending on an input level of an input optical signal. SOLUTION: An AMP 4 compares a voltage around a peak hold capacitor CP with a reference voltage VREF and feeds back its output corresponding to the quantity of the difference to an operational amplifier OP1. Then the PP1 continues outputting a positive logic Q when a data input is logical 1 till the data input and the value fed back from the AMP4 are coincident. While the positive logic Q is being outputted, the capacitor CP is charged, in which a peak value corresponding to the data input is stored. When a reset signal is given to a BUFF, a transistor(TR) 3 is conductive by an output of an AMP 3 and the charges in the capacitor CP are discharged. Thus, the peak hold value is reset and a wide dynamic range processing is implemented.
